Glass fiber-reinforced plastics (GFRP) based on polymer materials are widely used in lightweight impac-resistant structure design. In the process of design and development, it is very important to clarify the mechanical behavior under dynamic load to improve the product performance. Therefore, in this paper, Quasi-stati and dynamic compression behaviors of unidirectional continuous glass fiber-reinforced vinyl ester (GF/VE) composites with five kinds of fiber contents in the fiber direction were measured by an electro-hydraulic servo experiment system and a split Hopkinson pressure bar, and damage evolution of the material is analyzed by observing the microstructure of the cross section of the material. Results show that: The content of glass fiber affects the wettability between fiber and matrix, and the failure mechanism of material at high strain rate; Under quasi-static conditions, higher glass fiber content yields greater failure strength; Under dynamic conditions, as glass fiber content increases, toughness decreases, and the peak stress first increases and then decreases. Finally, the nonlinear viscoelastic constitutive model with damage evolution is derived, which can be used to predict the impact resistance of new composite structures in the product development and design stage and reduce the development cycle.

基于高分子材料的玻璃纤维增​​强塑料（GFRP）广泛应用于轻质抗冲击结构设计。在设计和开发过程中，明确动载荷下的机械行为对于提高产品性能非常重要。因此，本文采用电液伺服实验系统和试验系统对纤维方向上五种纤维含量的单向连续玻璃纤维增​​强乙烯基酯（GF/VE）复合材料的准静态和动态压缩行为进行了测试。分割霍普金森压力棒，通过观察材料横截面的微观结构来分析材料的损伤演化。结果表明：玻璃纤维的含量影响纤维与基体之间的润湿性以及材料在高应变率下的失效机制；在准静态条件下，玻璃纤维含量越高，破坏强度越大；动态条件下，随着玻纤含量增加，韧性降低，峰值应力先增大后减小。最后，推导了具有损伤演化的非线性粘弹性本构模型，可用于在产品开发设计阶段预测新型复合材料结构的抗冲击性能，缩短开发周期。
